Casement AL480
The strength and rich colour of aluminum with an oversized performance core for maximum thermal protection.
Commercial-grade strength, engineered in.
Initially designed for commercial high-rise applications, the Altitude+ casement provides superior protection against wind and rain, while its rich aluminum colour and slim sightlines keep the look residential.
A proprietary engineered performance core improves dimensional stability and raises deflection temperatures for increased strength — giving the series a real competitive edge.
Commercial-grade performance, residential warmth.
High structural performance
Initially designed for commercial high-rise applications, the Altitude+ window provides superior protection against wind and rain.
Sustainable
All building components are 100% recyclable or reusable, for a window that performs responsibly over its entire life.
Flexibility
Available in many configurations. Large windows are achieved through the creative use of structural mullions, continuous frames, or modular construction.
Performance Core
A new proprietary engineered material offering improved dimensional stability and higher deflection temperatures, resulting in increased strength — giving the Altitude+ series a real competitive edge.
